本文提出了一种利用现场可编程门阵列技术的基于面积高效动态环形振荡器的物理不可克隆功能设计。在高级计量基础设施（AMI）节点的整个使用寿命期间，为了满足美国国家科学技术研究所（NIST）的实时身份验证密钥和安全标准，需要生成大量的密钥来安全地对其进行身份验证。智能电表和公用事业中心之间的安全密钥交换方案在AMI网络中实现，同时使用轻量级加密保护电表的隐私和身份。提出的框架针对六个不同的安全级别（L0到L5）进行了演示，根据NIST标准，这些级别具有不同长度和鲁棒性的身份验证密钥。实验结果表明，我们的AMI方案满足NIST的实时要求（效率），安全级别为L1和L2，分别为6.45 ms和12.9 ms，比现有的技术要小得多。
In this article, an area-efficient dynamic ring oscillator-based physical unclonable function design utilizing field-programmable gate arrays technology is proposed. An enormous amount of secret keys are generated to securely authenticate advanced metering infrastructure (AMI) nodes throughout their useful lifetime meting National Institute of Science and Technology (NIST) real-time authentication key and security standards. A secure key exchange scheme between a smart meter and utility center is implemented within an AMI network while preserving the privacy and identity of the meter using lightweight encryption. The proposed framework is demonstrated for six different security levels (L0 to L5), which have authentication keys with different length and robustness according to the NIST standards. Experimental results show that our AMI scheme meets the NIST real-time requirements (efficiency) with security levels, L1 and L2, taking, respectively, 6.45 ms and 12.9 ms, which is considerably smaller than the existing techniques.
